According to my calc, to run LED's from 5V source you will need ~85 Ohm resisters in series for each led between the LED annode and the pic IO port to reduce the current down to 20mA each...
Thats assuming the LED's have a drive voltage of 3.3V
to work it out...
5 - 3.3 = 1.7V diference
now use V=IR re-aranged to R=V/I
Where,
V = voltage diference
I = Current in amps (mA is 1/1000A or 0.001A)
R = Resistance in ohms

I have 6 LEDs. The LEDS represent 2 H-bridges with 2 direction controls and 1 PWM per bridge. The resistors were 70 ohms, I changed all resistors to 220. It still did the same reset condition. I reprogrammed the board a few times changing nothing but fuse settings and It seems to work now. I have no idea why....I just flipped them one way and then the other and downloaded it.

An eye to the default value of the LVP bit ???

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
